cds-question@unistra.frexoplanetsinfrared-astronomyspectroscopyoccultationPlanets are like children with each one being unique and special. A better understanding of their collective properties requires a deeper understanding of each planet. Here we add the transit and eclipse spectra of hot-Jupiter WASP-74b into the ever growing data set of exoplanet atmosphere spectral library. With six transits and three eclipses using the Hubble Space Telescope and Spitzer Space Telescope (Spitzer), we present the most complete and precise atmospheric spectra of WASP-74b. We found no evidence for TiO/VO nor super-Rayleigh scattering reported in previous studies. The transit shows a muted water feature with strong Rayleigh scattering extending into the infrared. The eclipse shows a featureless blackbody-like WFC3/G141 spectrum and a weak methane absorption feature in the Spitzer 3.6{mu}m band. Future James Webb Space Telescope follow-up observations are needed to confirm these results.2021AJ....162..271Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/162/271CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AJ/142/39 : Sample of 114 {gamma} Doradus candidates (Henry+, 2011)J/ApJ/727/125 : Two secondary eclipses of WASP-12b with Spitzer (Campo+, 2011)J/ApJ/754/136 : Light curves of HD 149026b in 3.6-16um (Stevenson+, 2012)J/A+A/573/A90 : STAGGER-grid of 3D stellar models.
